Hello All, You also have to accept that, if it's on the user's PC and they REALLY want that data, they can get it. They don't even need to crack the encryption. They just need to figure out what key the program's using to unlock the DB. There's absolutely no way to protect data that's stored on someone else's PC. Just look at DVD's, HD DVD and Blu-Ray disks. Millions spent on security, cracked within months of release.
